, and D, lined To all whom it may concern: I

Be it known that I, XVILLIAM M. SUHR, of Brooklyn, in the county of Kings and State of New York,haveinventedanew and Improved Covering, ofwhich the following is a full,clear, and exact description. i

The object of my invention is to provide a new and improved covering specially adapted for covering and protecting pipes, boilers, walls, ceilings, &c., so as to prevent loss of heat and to render buildings fire-proof.

The invention consists of a filling of asbestos fiber, mineral wool, or similar noncombustible material inoloscd in an asbestos-paper covering lined on the inside or outside with a wire netting.

The invention also consists in the construction and arrangement of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1. is a cross-section of my improvement as adapted for pipes. Fig. 21s asimilar view of a modified form of the same. Fig. Sis a sectional elevation of my improvement in the form ot a sheet or block as used for walls and ceilings, and Fig. 4.- is a like view of a modified term of a sheet or block.

My improved coveringmcoording to the pur pose for which it is to be used, is made either in tubular form, as illustrated in Figs. 1 and 2, for covering pipes, 820.,01' in sheets or blocks of suitable dimensions for covering boilers, walls, floors,

My improved covering A consists of a fill- B, of mineral wool, asbestos fiber,or siminon-coinbustible material, which filling is scd between two asbestus-paper covers, 0

either on the inside or outside with a wire-netting, E, of suitable mesh. It will be seen that this wirenetting E stift'ens the covering materially, makes it more durable, and prevents the filling from falling apart in case the asbestos-paper covers are destroyed by the action of water, heat, or other injurious influences.

In order to prevent the filling B from shilting in the paper covers 0 and D,l. may employ a wirenetting or other pliable fabric, F, between layers of the filling, as illustrated in Figs. 2 and 3. This additional layer of pliable fabric also stiffens the entire coverin It will be seen that my improved covering can be used for covering steam-pipes, boilers, &c., to prevent radiation of heat; or it can be used to cover pipes so as to prevent their freezing; or it maybe employed in the form ot'sheets and blocks, as illustrated in Figs. 3 and l, for covering walls, floors, and ceilings of buildings to make the latter fire-proof.

Having thus fully described my invention, I

claim as new and desire to soon re. by Letters Patent 1. The improved non-conducting covering consisting of parallel layers or covers ot"asbestus paperand linings of wire-nctting and an interposed filling of asbestus fiber, all as shown and described.

2. As a new article of manufacture, a nonconducting covering consisti ug of outer and inner covers formed of asbestos paper, a. tilting of asbestus fiber inclosed by the said covers,and a piece of pliable stiflening matcriahwhich is arranged in the midst oi said lilting intermediate of the covers, as shown and described, for the purpose specified.
